Even a dialogue like this won't have much impact because there really isn't anything we can do now to hinder or stop their Invasion.
At the moment nothing can be expected of anything because indeed when sanctions are useless then one of the last hopes is to hope they stop this voluntarily although this is indeed very difficult to happen
Since Russia has maintained its position despite such sanctions, Russia's decision to end the war will be final. While other countries could boycott Russia's other things, Europe could not survive without Russian oil. So Russia's main power here is oil.
So even if they boycott other things, including gambling websites, there is no tension in Russia because they will sell oil and cover everything.
